Interesting write up I found. Connection between zero point energy, dark energy....

and borderlands? I do not have the time right now, but if anyone is good in Physics might be able to make a little more sense of HL2 with this.

Interesting.... That could explain why the combine are electrocuted when you pick them up with the super grav gun...

"The theory rests on many assumptions, and the one that worries us is the most fundamental: that the quantum vacuum produces a real electromagnetic field."

Haven't read much of it yet, will keep going

i've already posted a thread about the physics and maths about the h-l series. it truely is interesting.

Whow.. hard words..

Hmm, I'd assumed the Dark Energy reactor used Cold, Dark Matter *shrug*

it seems like zero point energy would stop/ slow gravity and other accelerations... remember those big blue gelatiny tubes?! ZPE i guess.
But i don't see how a gun would work...

I would not put much trust into that site. I skeemed through it and did find a few big mistakes in elementary physics. Just remember that ZPE could be just that, a place on the graph designated as zero. An example is AC voltage line where 0 is set midpoint between the peak and valley of the sine wave.
Also conservation of energy tells us that enegry can not be created, only converted, these guys however imply that they can get something out of nothing.
Like I said not worth much.
Dark energy is a theoretical energy similar to dark matter. Both are used to explain descrepancies in astronomical models. Dark energy is belived to be the foce that is causing our universe to expand. Kind of antigravity.
Hope this helps, and remeber kids its just a game, Valve is clever and many things in game tie in to real life, but its still science fiction, thats what makes it so cool

But only a couple of hundred years ago 'elementary physics' as were then were proved wrong, and 'new elementary physics' came into being.

It science, new things are discovered daily, and sticking with 'what we know to be true' is the way nothing new is learnt.

or is the world still flat

Um, no, the phrase "zero point energy" has a pretty specific meaning in science, and the article came pretty close to it. I don't know that they were right about everything, but they were obviously trying to talk about the same thing.

Also conservation of energy tells us that enegry can not be created, only converted, these guys however imply that they can get something out of nothing.

Yes, that's exactly what they're implying, isn't it?

The Casimir effect shows that you can get something from nothing. Even if it's on a scale that's inconsequential to things on the scale of everyday experience. The article makes too much of it; you can't get enough energy out of it to do anything useful. You can violate conservation of energy, but it's on an extremely small scale.
